I assume you are looking at an old version then, and Microsoft fixed this mistake in the meantime. Windows 10 header files contain for example:
--- snip --- FORCEINLINE VOID IoSkipCurrentIrpStackLocation ( _Inout_ PIRP Irp ) [...] { NT_ASSERT(Irp->CurrentLocation <= Irp->StackCount); Irp->CurrentLocation++; Irp->Tail.Overlay.CurrentStackLocation++; } --- snip ---
Nevertheless, I think both "{...}" and using an inline function is fine in this case.
It should be either an inline function (preferred) or a "do {} while(0)" block. A "{...}" block will cause syntax errors in some cases.
